How to Connect to the Web Gateway Sidecar and Utilize 'seed: path' in IKO 3.6

#Kubernetes #InterSystems IRIS

I am currently using IKO 3.6 to deploy an irisCluster on EKS, but I am facing some challenges. Firstly, I need assistance in understanding how to connect to the Web Gateway sidecar. If anyone has experience with this, I would greatly appreciate any guidance or advice you can offer. Secondly, I am trying to utilize the 'seed: path' options of irisDatabases, but I am unsure of the best approach. If anyone has successfully implemented this feature, I would love to hear about your approach and any insights you can provide. Thank you in advance for any help you can offer!

Hi Roy,

I can't tell about the "seed: path" but how to play with the Web Gateway sidecar you can follow this example :

https://community.intersystems.com/post/local-k8s-deployment-fhir-server

TL; DR :

In your topology definition :

## deploy webgateway (web server) nodes
    webgateway:
      image: k3d-registry.localhost:5000/intersystems/webgateway:2023.1.1.380.0-linux-amd64
      type: apache
      replicas: 1
      applicationPaths:
        - /csp/sys
        - /fhir/r4
      alternativeServers: LoadBalancing
      loginSecret:
        name: iris-webgateway-secret

The iris-webgateway-secret :

kubectl create secret generic iris-webgateway-secret --from-literal='username=CSPSystem' --from-literal='password=SYS'

The config file for iris :

[Actions]
ModifyService:Name=%Service_CallIn,Enabled=1,AutheEnabled=16
ModifyUser:Name=SuperUser,ChangePassword=0,PasswordHash=a31d24aecc0bfe560a7e45bd913ad27c667dc25a75cbfd358c451bb595b6bd52bd25c82cafaa23ca1dd30b3b4947d12d3bb0ffb2a717df29912b743a281f97c1,0a4c463a2fa1e7542b61aa48800091ab688eb0a14bebf536638f411f5454c9343b9aa6402b4694f0a89b624407a5f43f0a38fc35216bb18aab7dc41ef9f056b1,10000,SHA512
ModifyUser:Name=CSPSystem,ChangePassword=0,PasswordHash=a31d24aecc0bfe560a7e45bd913ad27c667dc25a75cbfd358c451bb595b6bd52bd25c82cafaa23ca1dd30b3b4947d12d3bb0ffb2a717df29912b743a281f97c1,0a4c463a2fa1e7542b61aa48800091ab688eb0a14bebf536638f411f5454c9343b9aa6402b4694f0a89b624407a5f43f0a38fc35216bb18aab7dc41ef9f056b1,10000,SHA512

To generate PasswordHash :

docker run --rm -it containers.intersystems.com/intersystems/passwordhash:1.1 -algorithm SHA512 -workfactor 10000

Add the configmap for iris :

kubectl create cm iriscluster-config --from-file common.cpf

the topology of IRIS + Webgateway :

apiVersion: intersystems.com/v1alpha1
kind: IrisCluster
metadata:
  name: sample
spec:

## provide InterSystems IRIS license key if required
#     licenseKeySecret:
#       name: iris-key-secret

## specify files used to customize the configurations of
## InterSystems IRIS nodes, including passwordHash parameter
## to set the default password, securing InterSystems IRIS
  configSource:
    name: iriscluster-config

## topology: defines node types to be deployed; only "data:" is required

  topology:
    data:
      image: k3d-registry.localhost:5000/iris-oauth-fhir-iris:latest


## deploy webgateway (web server) nodes
    webgateway:
      image: k3d-registry.localhost:5000/intersystems/webgateway:2023.1.1.380.0-linux-amd64
      type: apache
      replicas: 1
      applicationPaths:
        - /csp/sys
        - /fhir/r4
      alternativeServers: LoadBalancing
      loginSecret:
        name: iris-webgateway-secret

Thank you for sharing the information. I'm currently facing difficulties in establishing a connection with the sidecar web gateway and I'm uncertain about the process of obtaining the URL for its management portal. Furthermore, I would appreciate guidance on enabling external connections to the Kubernetes network, specifically for the sidecar web gateway.

Regarding the new topology.data.irisDatabases.seed field, the field is used to let you create databases that start with some starting data in them instead of the usual empty database.  This is useful for applications that typically start with some basic information in them.  Here's the link to the docs, if they help.
